Abstract: 900,894. Automatic temperature-control systems. ALLMANNA SVENSKA ELEKTRISKA A.B. Oct. 27, 1960 [Oct. 28, 1959], No. 36864/60. Class 38 (4). [Also in Group XL (a)] In a method of cooling the condensing chamber of a liquid cathode rectifier having a long, preferably horizontal, tank in which a current of cooling air is led longitudinally along the tank through a casing 2 surrounding the tank, a circuit sensitive to the temperature of the tank causes complete interruption of the air current when the temperature of the tank decreases to a fixed value and causes the current of air to be restored to full velocity when the temperature increases to a higher value. A thermistor 5 is placed half-way along the tank and is connected to the secondary 9 of a transformer, the two primaries 7, 8 of which and two resistances 13, 14 form an A.C. bridge circuit which is the control circuit of a 2-step amplifier. The bridge circuit output 17, 18 is fed via rectifier 33 to windings 31, 33 to increase the inductance of one and decrease the inductance of the other of two transductors 25, 25 1 and so to energize or de-energize two-phase motor 30 to open or close damper 4. The transductors form the other step of the amplifier and are supplied via rectifier 24, variable resistances 28, 29, and windings 26, 27. One winding of motor 30 is fed directly, the other via condenser 34. Air is circulated by fan 3 over the rectifier tank which may have cooling ribs, the area of which increases in the direction of flow of the air current. The mercury rectifier has main anodes in one or more rows as in Specification 848,310 and a cylindrical tank. Capacitor 11 is for reactive power correction and may, if desired, be across primary 9.
